I thought I had no colour frames for NGC 5005, but recently found some that
I took about a month later than the luminance.
Colour was 6x5 minutes each with 2xbinning.
5 minutes are probably a bit too long with 2xbinning at f/5.7, the green
channel had a background count of over 32000.
I also took some Halpha frames but didn't include them in the final version
as there were no HII regions visible even with Halpha.

I acquired the data for NGC 5005 in Canes Venatici two month ago, planning
to add colour later as this galaxy is moderately bright. As it looks like
I
won't get any colour this year I'll post the b/w version now.
Taken from the middle of Berlin with a 10" Meade ARC at f/5.7 on a G11
mount, SXV-H9 camera, 39x5 minutes.
